Subject [jira] [Updated] (YARN-4756) Unnecessary wait in Node Status Updater during reboot
Date Thu, 03 Mar 2016 19:17:18 GMT

     [ https://issues.apache.org/jira/browse/YARN-4756?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eric Badger updated YARN-4756:
------------------------------
    Description: The startStatusUpdater thread waits for the isStopped variable to be set
to true, but it is waiting for the next heartbeat. During a reboot, the next heartbeat will
not come and so the thread waits for a timeout. Instead, we should notify the thread to continue
so that it can check the isStopped variable and exit without having to wait for a timeout.
